How to add holes to an extruded path object - I wish to modle a filmstrip
Start with a flat plane (film strip) and make an array of perforations (using a couple arrays) to punch holes in the plane. I have used academy 4 perf per frame here. I start with a box outside of the film plane, so that I know where it would appear o the previous film frame.





Then we array the plane, which has holes in it, and fit that to a curve. Make sure that all of the objects have their Origin Cleared at the centre (Alt-C).









BEWARE! Down't rotate the curve in the normal Z direction (up) as this will cause the film strip to pinch along the side which it would not do.



EDIT: Bonus material using a UV unwrap.
